Just a thought, I had to Google the word "frothy" in conjunction with the name Santorum to find out why the nickname is used. Now I know. This is why we need more limits on free speech.
What specific limits to people’s free speech do you suggest?
If the intent is to inflict suffering on a person or damage his reputation using obscene terminology. There is no excuse for it, no benefit to humanity, and it's not even funny! In a closed setting, like a live comedy act, it is perhaps different.
Thank God we have you to determine what is and isn't funny!
